Abstract
The invention discloses a cane sugar stanizing method. The method comprises the following steps that cyclohexane and dimethyl formamide are adopted as reaction media, and cane sugar and dibutyltin oxide react for 4-6 hours at the temperature of 92-95 DEG C, so that dibutyltin oxygroup cane sugar is obtained, wherein the mass ratio of the cyclohexane to the dimethyl formamide is 1: (2.8-2.9), and the mass ratio of the cane sugar to the dibutyltin oxide is 1.25: 1. Compared with existing cane sugar stanizing methods, by means of the method, the cane sugar stanizing conversion rate can reach 95% and above.
Description
Technical field
The present invention relates to a kind of tin method of sucrose.
Background technology
China is that sweetener uses big country, and sweetener uses total amount up to 150,000 tons/year. But, just started in recent years to makeWith Sucralose, according to China's existing market investigation, the use of Sucralose only accounts for 1% left and right wherein, is about 1500 tons/year.
Sucralose is at present unique functional sweetener of producing taking sucrose as raw material, and property class is sucrose seemingly, without anyBitter aftertaste, empty calory, not carious tooth, good stability.
Though Sucralose has high sugariness, be not absorbed by the body, do not produce heat, be therefore diabetes, high blood pressure, the heartThe patient's such as cerebrovascular disease, obesity good sweet taste substitute, is widely used in food and medicine industrial production.
Estimate 5 years from now on, people are more and more higher to the requirement of environmental protection food, and China will ratify more foodKind is used Sucralose, and this will promote the use of China's Sucralose greatly.
Sucralose is generally taking sucrose as raw material at present, obtains successively through tin, esterification, chlorination, de-acyl reaction.
Summary of the invention
The tin step the object of the invention is during existing Sucralose is produced is improved, and transforms to improve sucrose tinizationRate, provides a kind of tin method of sucrose.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A tin method for sucrose, comprises the steps:
Taking cyclohexane and dimethyl formamide as reaction medium, sucrose reacts 4-6 hour with Dibutyltin oxide at 92-95 DEG CObtain dibutyl tin oxygen base sucrose, wherein, the mass ratio of cyclohexane and dimethyl formamide is 1:(2.8-2.9), sucrose and twoThe mass ratio of butyl tin oxide is 1.25:1.
Further, the mass ratio of sucrose and dimethyl formamide is 1:(3.7-3.8).
Compared with the tin of existing sucrose, the present invention is optimized tin condition, and the conversion ratio of sucrose tin is reachedTo more than 95%.
Detailed description of the invention
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only usesIn description and interpretation the present invention, be not intended to limit the present invention.
Embodiment 1
1115.6g sucrose, 892.5g Dibutyltin oxide, 1488g cyclohexane and 4240g dimethyl formamide are added to reactorIn, back flow reaction 5 hours at 92-95 DEG C, obtains 1803g dibutyl tin oxygen base sucrose, and conversion ratio is 95%, reacts as follows:
。
Embodiment 2
370g sucrose, 296g Dibutyltin oxide, 500g cyclohexane and 1405g dimethyl formamide are added in reactor,Back flow reaction 4 hours at 92-95 DEG C, obtains 598g dibutyl tin oxygen base sucrose.
Finally it should be noted that: the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention,Although the present invention is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still canSo that the technical scheme that aforementioned each embodiment was recorded is modified, or part technical characterictic is wherein equal to replacement.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., all should be included in of the present inventionWithin protection domain.
